Abstract: PURPOSE: To obtain the bright display featuring a high visual property by applying the voltage of two different levels except zero volt to the liquid crystal featuring the cholesteric spiral structure.  
     CONSTITUTION: Glass substrate 1 and 2 are opposing to each other with a distance of about 10 m, and transparent electrode patterns 3-1W3-3 and 3-1'W3-3' plus orientation layer 4 and 5 to give orientation to liquid cyrstal molecule 11 are formed respectively.

The original orientation of molecule 11 is like arrangement 18 and transparent with no light dispersion. The DC or AC voltage of about 8V is applied between the electrodes to secure arrangement 9, and molecule 11 is arranged vertically to substrate 1 and 2 and transparent. If the application voltage is lowered down to about 3V, molecule 11 is arranged with its spiral axis nearly parallel to substrate 1 and 2 like arrangement 10. Thus, minute domains are formed at random, and thus the light is scattered intensively to ensure the bright and steady display.

Filed: 1986-07-03
Abstract: PURPOSE:To obtain an accurate inter-line correlation by using three-line-share of picture element signals and a necessary signal to detect a line strengthened in correlation, obtaining the value of ratio of the necessary signals between the lines. CONSTITUTION:By subtractors 401 and 402, the difference signal Yn+1-Yn between the Yn+1 and the Yn, and that Yn+1-Yn+2 between the Yn+1 and Yn+2 are respectively generated. The magnitude relations between the absolute values of the above difference signals ¦Yn+1-Yn¦ and ¦Yn+1-Yn+2¦ and a set value A are detected by comparators 403 and 404. Magnitude relation detection signals from the comparators 403 and 404 are inputted to a judgement circuit 405 from which a control signal 406 to select a line having the closest correlation with the necessary signal Yn+1 is outputted. Consequently, the value of ratio supplied from a ratio calculation device 103 comes close to '1', narrowing the extent of arithmetic operation. As a result, the accuracy of the arithmetic operation can be upgraded.

Filed: 1983-08-25
Abstract: PURPOSE:To plant a seeding at a fixed depth to mud surface regardless of uneveness of the tilled land by vertically changing the position of an advance driving wheel quickly and assuredly. CONSTITUTION:When the tilled land is in the state of rising, a machine body is inclined by a driving wheel 10 to change the depth of planting a seeding.

Title: Self-reset type overcurrent protection element
Inventor: ABE TOSHIAKI
IPC: H01C7/02
Filed: 1990-06-15
Abstract: PURPOSE:To prevent a crack of an armoring material while generating no electrode coming off for maintaining electric reliability over a long period by making a coating material of a main element to have tensile stress not exceeding a specific value in a prescribed elongation percentage and an elongation percentage not less then a specific value at a time of destruction. CONSTITUTION:This self-reset type overcurrent protective element uses an electroinsulating material having tensile stress not exceeding 0.45kgf/mm<2> in an elongation percentage 10% and an elongation percentage not less than 5% at the time of destruction as a coating material so as to reduce a degree of suppressing thermoexpansion of a main element 8 at a current limiting time and to increase thermoexpansion of the main element. Because of increasing thermoexpansion of the main element, the number of contacts between inner conductive particles decreases so that a resistance value at the time of current limiting is increased. Accordingly, a PTC(positive temperature coefficient) characteristic at the time of current limiting increases. Further, due to a big elongation percentage, no crack of the armoring material is generated inspite of thermoexpansion of the main element.
